• Patient-specific cranial implant produced with 3D Systems’ point-of-care additive manufacturing technologies used in pioneering surgery at University Hospital Basel (Switzerland)
  • 3D Systems’ technologies enabled first 3D-printed cranial implant used in surgery at Salzburg University Hospital (Austria)
  • Company’s additive manufacturing technologies enabling advances in cranial implants market — anticipated to reach more than $2 billion by 2030

ROCK HILL, South Carolina, October 17, 2023 – Today, 3D Systems (NYSE:DDD) announced a patient-specific 3D-printed cranial implant produced using its point-of-care technologies was successfully used in a cranioplasty at the University Hospital Basel (Switzerland). Under the leadership of Prof. Florian Thieringer, head of the Medical Additive Manufacturing Research Group (Swiss MAM) at the University Hospital Basel's Department of Biomedical Engineering (UNIBAS DBE), and the Department of Oral and Maxillofacial Surgery (OMFS), in collaboration with Prof. Raphael Guzman and the Department of Neurosurgery, the team employed 3D Systems’ technologies to produce the first cranial implant at the point of care that complies with the current Medical Devices Regulations (MDR). 3D Systems’ extrusion printing technology is unique as its architecture and design are easy to use to produce durable, biocompatible implants using Polyetheretherketone (PEEK) material. Additionally, the technology enables the production of patient-specific geometries at the hospital itself providing tremendous benefits to both surgeons and patients. The implant created by the team at University Hospital Basel was used to successfully replace a section of disintegrating skull in a 46-year-old male who was experiencing complications from a stroke in 2019. 

Example of a cranial implant produced using VESTAKEEP® i4 3DF PEEK by Evonik on 3D Systems’ EXT 220 MED extrusion platform.

When the patient first entered Prof. Guzman’s care, he was experiencing visual disturbances, severe headaches, and dizziness, and his forehead was sinking due to a disintegrating skullcap. The University Hospital Basel team under the guidance of Dr. Neha Sharma, Ph.D. first took a computed tomography (CT) scan of the patient’s skull and imported that into software to create a model of the implant customized to his unique anatomy. The implant was then produced in the Hospital’s 3D printing lab using VESTAKEEP® i4 3DF PEEK by Evonik on 3D Systems’ EXT 220 MED extrusion platform. PEEK is a very desirable material for such applications due to its mechanical properties (i.e., lightweight, resistant to thermal and ionizing radiation, and similar to human bone). 3D Systems’ printing technology has been uniquely engineered to enable healthcare applications within sterile environments.

“The successful implantation at the University Hospital of Basel is a pivotal moment for medical 3D printing, demonstrating its potential to revolutionize patient care,” said Prof. Thieringer. “Our collaboration with hospitals across Europe, along with the invaluable expertise provided by POC APP AG around QMS and regulatory guidelines, showcases the power of advanced technology and collaboration in improving healthcare outcomes.” 

3D Systems’ point-of-care solution was also successfully used by a team at Salzburg University Hospital, Department of Oromaxillofacial Surgery, to produce a patient-specific cranial implant for a 55-year-old male, Mr. Rainer Trummer, who suffered from craniosynostosis (i.e., one of the cranial bones ossified too early during childhood, resulting in a deformation of the skull). These technologies were brought together by the hospital’s in-house clinicians to successfully address the patient’s needs, providing a customized solution that best positioned the team for success. The hospital used Oqton’s D2P® software to create 3D models from the patient's CT images and Oqton’s Geomagic Freeform® to complete the design of the patient-specific occipital prosthesis. The cranial implant was printed using VESTAKEEP® i4 3DF PEEK by Evonik on 3D Systems’ EXT 220 MED extrusion platform.

The solution has also been successfully deployed at the Department of Neurosurgery, University Hospital Salzburg, for patient-specific implants after decompressive craniectomy, which is regularly performed for aggressive brain swelling. According to Prof. Christoph Griessenauer, chairman of the department for neurosurgery in Salzburg, 40 decompressive craniectomies are performed in Salzburg annually. After the swelling subsides, the bone is replaced with a patient-specific cranioplasty implant. So far four cranioplasty surgeries have been performed within the last month, and multiple more are planned for the future. “We are proud now to use for the first time a patient-specific cranial implant printed at our hospital,” said Griessenauer. One of the departments’ senior attendings, Dr. Pöppe, was spearheading this effort from the clinical side. “This revolutionary procedure showcases the power of medical 3D printing in providing personalized solutions that adhere to regulatory standards. The success of these procedures marks a significant step forward in the integration of 3D printing into routine clinical practice,” said Dr. Pöppe. 

"We are proud to be at the forefront of this medical revolution, leveraging our expertise in 3D printing to bring tangible benefits to patients," said Stefan Leonhardt, director, medical devices, 3D Systems. "Our collaboration with hospitals in Europe demonstrates the potential of 3D printing to transform healthcare, and we are excited to continue advancing this technology to address a broader range of medical needs. 3D Systems remains committed to driving innovation in the field of medical 3D printing, working hand in hand with healthcare professionals to enhance patient care and contribute to a brighter, healthier future.”

It is anticipated that the use of 3D-printed cranial implants will accelerate based on the availability of advanced technologies. According to a report released by Acumen Research and Consulting in February 2023, the cranial implants market size in 2021 was roughly $1.2 billion and is anticipated to approach $2.1 billion by 2030. Cranial implants can address a breadth of applications including trauma, defects, and reconstruction. The continued innovation in materials and manufacturing methodologies such as 3D printing are expected to enable new solutions to catalyze growth in this market.
